Why hire an experienced B2B portal development company
Building a B2B portal is different from consumer ecommerce. You need multi-tier pricing, approval workflows, and ERP integration.
B2B portals handle complex business rules. A single order might require manager approval, credit check, and inventory hold across 3 warehouses. We use event-driven architecture with Apache Kafka to manage these workflows reliably. Our portals handle 10,000+ concurrent buyers without page load delays.
We have built portals that integrate with SAP, Oracle NetSuite, and Microsoft Dynamics. Our team writes integration tests with WireMock so your ERP data stays in sync. Every portal ships with an admin dashboard that shows order volume, approval times, and supplier performance metrics.
Generic dev shops vs. an experienced B2B portal company
Most agencies build one-page apps. B2B portals need multi-tenant architecture, complex pricing, and ERP sync.
A generic web development agency might build your B2B portal with WordPress and WooCommerce. That works for a handful of users, but breaks when you onboard 500 suppliers or add role-based pricing. We build portals from scratch with Next.js, PostgreSQL, and Redis for performance.
Our portals handle 50,000 SKUs with multi-currency pricing. We use GraphQL for real-time inventory queries. Every portal includes Webhook-based sync to your ERP system so orders, invoices, and shipments stay in sync automatically.

How we build your B2B portal in 12 weeks
Our process has 4 phases. You get a working portal with real users by week 12.
Phase 1 is the Roadmap. We spend 2 weeks defining user roles, portal features, and the data model. You get a fixed price quote and a timeline document. Phase 2 is the Product build where we code the backend, frontend, and integrations in 8 weeks.
Phase 3 is Release where we deploy to production, run load tests, and hand over admin access. Phase 4 is the 30-day warranty where we fix any issues. You own the full source code from day one.
What ships with every B2B portal
You get the portal code, the deployment pipeline, and the documentation to maintain it yourself.
We don't just hand you a zip file. Every portal ships with a production-ready infrastructure. You can run the portal yourself or let us host it on AWS with 99.9% uptime SLA. We include monitoring, logging, and error tracking from day one.
The codebase uses TypeScript with full type coverage. We write unit tests with Jest and integration tests with Cypress. Your internal team can read, modify, and extend the code without calling us.
- Source code in your GitHub repo
- CI/CD pipeline with GitHub Actions
- Docker containers for local and staging
- Terraform scripts for AWS infrastructure
- Sentry error and performance monitoring
- Lograge structured logging with Datadog
- PostgreSQL database with automated backups
- Redis cache layer for product catalog
- Stripe Connect integration for payments
- Role-based access control with 3 user types
What we ship in this practice.
Industrial parts distributor procurement portal
A midwest distributor needed a portal where 200 contractors could order replacement parts. We built a Next.js portal with real-time inventory from their Oracle NetSuite ERP. Order errors dropped by 60% and sales reps saved 15 hours per week on phone orders.
Medical device supplier self-service portal
A medical device company onboarded 50 suppliers in 3 months. The portal automated document collection, pricing uploads, and compliance checks. Supplier onboarding time went from 4 weeks to 3 days.
Lumber wholesaler B2B ecommerce portal
A lumber distributor replaced their fax ordering system with a React-based portal. Buyers see live pricing per tier, place bulk orders, and track delivery trucks. Average order size grew by 35% in the first quarter.
Electronics components marketplace
An electronics distributor launched a multi-vendor marketplace for surplus components. We built the platform with Stripe Connect for escrow payments and Algolia for product search. Monthly GMV reached $2M by month 6.
Logistics freight broker portal
A freight broker needed a portal where carriers could bid on loads. We built a real-time bidding system with Node.js and WebSockets. Carriers submit bids in under 2 minutes and brokers award contracts instantly.
Hotel supply chain portal
A hospitality group built a portal for 300 hotels to order linens, toiletries, and food supplies. The portal integrates with their Microsoft Dynamics ERP. Each hotel manager saves 6 hours per week on ordering.
Why teams hire us.
We have built 40+ B2B portals
IRPR has shipped over 200 software products, and 40 of them are B2B portals of varying complexity. We have integrated with SAP, Oracle, NetSuite, and many legacy ERPs. Our team knows the common pitfalls.
Fixed price, not hourly billing
After the 2-week Roadmap phase, we give you a fixed price quote. No hourly billing, no scope creep fees, no surprise invoices. The price you see covers the full portal build with integrations.
Senior engineers only, no juniors
Every developer on your project has 7+ years of experience. We do not staff juniors or offshore teams. Your portal is built by senior engineers who type in TypeScript and review each other's code.
Multi-tenant architecture from day one
We design every portal as a multi-tenant system with data isolation per buyer or supplier group. This means you can onboard new partners without rewriting the database. We use row-level security in PostgreSQL.
Compliance built in, not bolted on
If your portal handles payments, we make it PCI-DSS Level 1 compliant. If it handles medical supplies, we make it HIPAA compliant. We add encryption at rest, audit logs, and role-based access as standard features.
You own the code and the infrastructure
After the project, you have full ownership of the source code, CI/CD pipeline, and cloud infrastructure. You can maintain it yourself, hire another team, or let us host it. No lock-in, no licensing fees.
